A system includes a fluid controller coupled to an inflatable bladder and configured to add fluid to and remove fluid from the inflatable bladder, a control unit configured to provide information used by the fluid controller to adjust the pressurization of the inflatable bladder, the control unit including a user interface configured to constantly display a plurality of indicia corresponding to a range of pressure levels in which the inflatable bladder is employed by a user, where each of the plurality of indicia is associated with a different level of pressure of the inflatable bladder, respectively. In one embodiment, the fluid controller is configured to adjust the pressurization, in response to a user input at the user interface, to a pressure level selected by the user based on a current pressure level of the inflatable bladder, the pressure level selected by the user and an operating time of the fluid controller. In a further embodiment, a first indicia included in the plurality of indicia is associated with the current pressure level and a second indicia included in the plurality of indicia is associated with the pressure level selected by the user.
